12 Claims.

I This invention relates to improvements we. terclosets, particularly .to-the watercloset bowl and water supply and valve control means therefor A,

The objects :of the invention are:." r

First, to provide such a water closet havin an annular water supply conduit to the bowl and having an auxiliary jet under strong pressure-at the bottom of the'bowl.

Second, toprovidefan improved valved water supply, organized in connection with the ball.

cock, for delivering water by gravity to the upper annular conduit supply and. also delivering water under strong pressure,- as a jet, in the bottom of the bowl.

Third, to provide a special. valve structure with automatic float and control. means 'forthe purpose of delivering-water by gravity from a tank and by direct water main pressure.

Objects pertaining to details and economies of construction and operation will appear from the detailed description to follow. Preferred embodiments of my. invention are illustrated in the g accompanying drawings, in

which:

The parts will be identified by their: numerals of reference which are the same inIall the views.

1 is a water closet bowl. It is provided with an' ball cockvalve, and 13 is the'float whichconmain. passage 1'73.

3 is the .dis-

10 isthe overflow. pipeof usual construction. 11 is the supply pipe, 12 is the.

trols thesarne. 14 is the supply pipe leading to the ball cock valve, and 15 is the refill pipe leading from the valve chamber upwardly and around over intothe overflow pipe 10. 16 is the auxiliary supply pipe extended below the tank 6 at 161 to the auxiliaryjet passage 5.. l'listhe auxiliary valve casing.

Ball cook 12 is provided with a conical valve" seat 121 againstwhich closes the poppet valve 122. A cylindrical'bushing 1231s provided within the valve casing and a counterbalanced cylindrical spool-shaped plunger 124 reciprocateswithin this casing, being provided withhydraulic (cup, packings 125 125' at each end and being provided withv a central bore, whereby-the plunger will be counterbalanced by an equalpressure of water at both ends. The throw of tending through stufiing box 127. e 131 is fulcrumed at 132toears 133on the side ofthe casing of valve 12 and hasa rounded inwardly projecting short arm 134 engaging between the end flanges of the plunger 124. .This, provides avalve the operation of'which isreadily adjustable and is very free'in its movements,.

which is required for a structure of this kind.

- The outlet-128 of theball cock valve 12 leads into the casing 171 01' the auxiliary valve mecha nism '17. This valve casing is provided with an intake chamber 172 and an outlet chamber 173- delivering downwardly through pipe 14, whereby the tank 6 is filled. This is the main' supply.

,Valve casing-1'7 is also provided with discharge chamber 1'74 :to supply the pipe 16 to the auxiliary jet under direct pressure from the main;

Valve 18i is-provided for controlling the 110w of theplunger is adjustable by" set screw'1'26 .ex-

Float lever water through the auxiliaryvalve. In its lower position it closes valve seat 181 and prevents the direct flow otwater from chamber 172 to the is the valve seat 183 controlling the supply to the "chamber 174.

18 is raised 'agains'twthe valve seat 183, the supply of water to the passage 1'73 and auxiliary passage 16 "is cut off and water is delivered directly pipe 14 for filling the tank.

' The action of the valve 18-is controlled autoinaticallylby the*diapl"lragn1, plunger and float 'means. Ina recess 175 below valve 18 is dis- Valve 18 is provided withv "a vertical stem 182 and within the casing 171 through the supply chamber 173 to the Valve seat 183 is directly abovethe valveseat 181 so that when the valve posed a diaphragm 19 which is clamped at its 3 periphery by "bottom cover plate 20; T0 the center of this" diaphragm is secured the vertical plunger 21.. The plunger 21 is disposed axially under. valve 18, and, when it is raised, elevates the valve to the dotted position indicated in Fig. 3, closing part 183. This is accomplished when the diaphragm is acted upon. automatically by hydraulic pressure. A cylindrical chamber 201 is formed centrally beneath the diaphragm 19 in the cover 20. A restricted passage 202 203 through hollow screw 22 delivers into the upper 5 part of chamber 201 directing a jet radially and centrally into the same. The lower partof the chamber is provided with outlet 204 connecting to a central bore 205 terminating in a valve seat 206 above. A dish-shaped valve 23 cooperates with the valve seat 206. This valve is a float valve provided with a central stem 231 a tached to a screw and suspending a float 233 at its lower end. Limiting stop collar 232 is pro vided on the valve stem 231. The float'chamber 24, having a bottom aperture 241 vented at the top at 242, embraces the said float 223 and is disposed below the said valve chamber 17 and attached thereto by suitable head as shown.

v The parts of my improved water closet structure have thus been completely described in the preferred form. The operation will be described in detail.

, When the lever 9 is tripped, the valve 8 is raised and the water in the tank drops by gravity through pipe 7 to the annular supply passage. This permits the float 13 to drop and the valve 122 is raised from its seat 121. Water under pressure at once rushes into the discharge open- '615 ing 128 into chamber 1'72, above valve 18, up past valve seat 183, into discharge chamber 174 into pipe 16, and thence down through the auxiliary passage 5, delivering a strong jet of water under direct pressure from the main 5.. across the bottom 4 of the bowl.

' This action continues with increasing strength as the valve 122 is raised, thus securing a very strong jet discharging action across the bottom of the bowl into the siphon 3. 49;. the tank descends, it eventually drops below the valve casing 24 and permits water to flow out 7 through the aperture 241, permitting float 233 to drop. This carries down valve 23 by its connection to the valve stem 231. As soonas valve 23 seats at 206, chamber 201 is substantially closed and water under pressure enters and acts upon the diaphragm 19 carrying plunger 21 upwardly against valve 18, lifting it against the seat 183 and cutting off the auxiliary water 59 supply to the jet.

Valve 18 closes against seat 183 and is maintained there until the float 233 raises float valve 23 off its seat. When this is done, water from r the chamber 201 is at once discharged and the pressure on diaphragm 19 is released, the plunger 21 dropaand by this time valve 122 has been closedonto its seat 121, pressure is released, and valve 18 drops into its seat 181 and the H water closet is again readyvfor operation.

In, the meantime, during theseoperations, sufficient pressure is in the chamber 171 to deliversufficient water through the refill pipe 15 to refill the bowl. 7

5 It will be seen that the structure is completely automatic. However, the valve 18 may be provided with mechanical trip means; as illustrated in Fig. 4, for returning it to initial position. This, however, would require special manipula- 7 tion and is not so desirable. A manual lever 25, acting upon a packed plunger 26, would be used for the purpose. The diaphragm would thus be forcibly depressed and turn pressure into the auxiliary passage which would be closed by the action of the parts at the proper time.

As' the water inv Any suitable means may be provided to control the pressure jet in the bottom of the bowl.

In certain instances it is desirable to connect the auxiliary pressure to the annular passage 2, when the bowl would be filled by a usual main connection.
